The call came on a Tuesday morning. Woman named Sandra, voice shaking. She'd paid a contractor $31,000 for a kitchen and bathroom renovation. The plumbing rough-in was supposed to take four days. Two weeks later, the pipes were exposed, nothing was connected, and the contractor had stopped answering his phone.
I walked in that afternoon. What I saw made my jaw tighten.
The supply lines were run with the cheapest PEX fittings you can buy at a big-box store. No copper where code demanded it. Drain lines pitched the wrong direction — water would pool, not flow. The vent stack? Never even started. But the invoice said "plumbing rough-in complete — $4,700."
She paid for work that literally did not exist.
I've been painting and renovating in the Bahamas since 1992. I've walked into the aftermath of this exact situation more times than I can count. And here's what I know: plumbing rough-in is where homeowners lose the most money without ever realizing it.
Why Plumbing Is the Easiest Place to Get Taken
Everything else in a renovation you can see. Drywall, paint, flooring — it's right there in front of you. You can touch it. You know if it looks right.
Plumbing rough-in disappears behind walls. You can't inspect it after the fact without tearing everything open. And most homeowners don't know enough to inspect it before the drywall goes up.
Bad contractors know this. They count on it.
What Nobody in the Trade Will Tell You
Here's the thing: a real plumber carries specific tools. Not just any tools — the right ones. And the tool that tells you more about a plumber than any license or reference is a quality pipe wrench.
I'm not a plumber by trade, but I've watched enough of them work over 34 years to know the difference between someone who respects the craft and someone who's cutting corners. A plumber who shows up with a RIDGID 31060 pipe wrench — the 14-inch straight model — is someone who invested in their trade. That wrench has a forged steel hook jaw and heel jaw that grip without slipping. It's not a knockoff. It's not an adjustable crescent wrench they're using because they're too cheap to buy the right tool.
If your plumber is trying to do rough-in work with the wrong tools, walk away. That's not a small thing. That's a mindset. And that mindset will cost you.
Three Things to Check Before You Pay for Plumbing Rough-In
1. Demand to see the work before the walls close.
This is non-negotiable. Any contractor who refuses to let you inspect rough-in work before drywall is hiding something. Period. You don't need to be an expert — you just need to be present. Take photos. Ask questions. If they get defensive, that's your answer.
2. Know the difference between supply and drain lines.
Supply lines bring fresh water in. They're under pressure. They need to be run clean, with proper fittings — copper or PEX, depending on code. Drain lines carry waste out. They need pitch — at least 1/4 inch per foot. If a drain line looks flat or runs uphill, it's wrong. You don't need a degree to see that. You just need to look.
3. Verify the vent stack exists.
Every plumbing system needs ventilation. Without it, drains gurgle, traps siphon dry, and sewer gas enters your home. If you don't see a pipe running up through the roof from your new bathroom or kitchen, ask where it is. If they can't show you, don't sign off.
What the Uninformed Homeowner Does:
Signs the draw request. Trusts the contractor's word. Figures "they're the professional." Pays $4,700 for rough-in that was never completed, then pays another contractor to tear it out and redo it.
What You're Going to Do Now:
Walk the job site before the drywall crew arrives. Take your phone. Take photos of every pipe, every connection, every fitting. Ask the plumber to walk you through what they did. If they can't explain it clearly, that's a red flag. If their tools look like they came from a bargain bin, that's another.
You didn't hire a contractor to gamble your savings. Plumbing rough-in is not the place to be polite and hope for the best.
And if you're the kind of homeowner who wants to understand what quality work actually looks like — the kind who'd rather spend an hour learning than a week regretting — I keep a RIDGID 31060 14-inch pipe wrench in my own kit. Not because I'm a plumber, but because when I walk a job site, I can tell in 30 seconds whether the crew working there invested in their craft or not. You can grab the same one here. It's about $40. The lesson it teaches you about what real tools look like is worth ten times that.
For cutting pipe clean — and I mean clean, no burrs, no crushed edges — the plumbers I trust use the RIDGID 32013 pipe and tubing cutter. If your plumber is cutting copper with a hacksaw and calling it good, you're looking at future leaks. That cutter runs about the same price. Cheap insurance.
